Abstract
This paper investigates the dynamic behavior of an offshore Wind Power Plant (WPP) based on Permanent Magnet Synchronous Generator (PMSG) connected through VSC-HVDC. Models and equations that describe different components of the PMSG are addressed and implemented. The control system of the back to back converters is developed for capturing the maximum energy from varying wind speed. Also, a detailed model for the VSC-HVDC is implemented and its controllers are developed. The offshore VSC station controller is based on positive sequence controller only, while the onshore VSC station is based on positive and negative sequence controllers. The negative sequence controller is used to mitigate the oscillatory power components and the corresponding DC voltage ripples caused by asymmetrical faults. A PSCAD/EMTDC study is performed to analyze the performance of such WPPs.
